Hello.
Whenever I see a question like this, it makes me sigh, because it implies that controlling female sexuality is still very important to many folks.
The concept of "virginity" dates back to a period of time in which women were considered property--and damaged property if they had experienced penis-vagina (p-v) sex. I don't know why you're asking this question, but let me give you some general information.
Most modern women don't have hymens, regardless of whether they've actually experienced p-v sex--and some have partial hymens. This is because women are much more active now, and hymens are frequently torn during bicycle riding, skiing, and other kinds of physical activities. Thus, a hymen that is notched or missing a section, such as you report, is not the result of p-v sex, but rather of some sort of physical activity or non-p-v sexual activity. Penis-vagina sex would most probably result in no hymen at all.
Hello.
The information I gave you is common knowledge among medical professionals. If you do a search for "hymen," you'll find many reputable medical sites with this information. Here's an example:
